HENRY O. KEELER, OF OGDEN, UTAH TERRITORY.

AUTOMATIC WElGHlNG-SC ALE.

SPECIFICATION forming part of Letters Patent No. 311,010, dated January 20, 1885.

Application filed April 7, 1884.

To aZZ whom it may concern.-

Be it known that I, HENRY O. KEELER, of Ogden, in the county of Veber and Territory of Utah, have invented a new and Improved Weighing-Scale, of which the following is a full, clear, and exact description.

My invention relates to scales having a revolving ial and a stationary pointer; and it consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate U corresponding parts in both the figures.

Figure 1 is a sectional elevation of the case inclosing the beam and its adjuncts, and Fig. 2 is a section of Fig. 1 on the line x x.

The beam a has its fulcrum at Z). The platform a is suspended from the beam at d, and the long arm of'the beam has the usual weighthanger, e, for the weights f, employed to balance the quantities greater than the capacity of the graduated portion of the scale. The pendulum-weight g is pivoted to the casing, and is connected with the short arm of the beam, as usual in the employment of such weights. I now propose to substitute a revolving dial, h, and a stationary index, t, for the movable index and stationary dial commonly used with pendulum-scales, by attaching a toothed segment, j, to the scale-beam a, which segment is constructed on the radius of the fulcrum b, and gears with a pinion, 70, on the shaft Z, on which the dial is mounted, to be rotated by the swing of the beam. The segment and the pinion are duly proportioned for causing the dial to make one revolution by the swing of the beam through the range of its travel. It will be seen that with a dial thus arranged the graduation of the scale may be very much larger and plainer than with a pointer of equal radius.

For the convenience of reading the record from both sides of the case at I arrange the shaft Z to extend across the inclosed space from side to side of the case, and fit a dial, h, on each end, with an index, 2, for each dial, and

(No model.)

with a glazed opening, 12, through the case for each ,dial. The shaft Zis supported by the brackets 0, attached to the sides of the case on below the dials, and having an offset at p, projecting thence back ofthe sides of the case, suitably to enable the dials to be located between the brackets and close to the sides of the case. An especial advantage of this arrangement is that the record of the weight may always be seen at one and the same place and through a small glazed opening, instead of having to follow the pointer along the whole range of its movement, and for this reason the invention will also be useful with beams having the usual shifting weights, with which it is sometimes desirable to use an index and scale.

If desired, but one dial may be used, as in the cheaper class of scales.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the shaft Z, the pinion 7c, dial h, and pointer 71, of the beams (1, provided with the toothed segmentj,the pendulum-weight g on the short arm of said beam, and the platform 0, suspended from the beam a between its fulcrum and the pendulumweight, substantially as herein shown and described.

2. The combination, with the shaft Z, pinion k, dial a, and fixed pointer 'Z, of the beam a, provided with the toothed segment the pendulum-weight on the short arm of the beam, the weighthanger e on the long arm of the beam, and the platform 0, substantially as herein shown and described.

The combination, with the casing m, provided with opposite openings 71. and fixed pointers i, of the shaft Z, journaled in supports in the case, and provided with the dial it and the pinion 7t, and the beam a, provided with the toothed segment j, the pendulumweight g, and the suspended platform 0, substantially as herein shown and described.
